摘要
应用灰色关联度分析法对影响彩色杂交棉组合F1代皮棉产量的主要因素进行综合分析,比较其灰色关联度,结果表明:彩色棉F1代杂优组合皮棉产量与各农艺性状之间的关联度大小依次是:衣分>株铃数>果枝数>667m2株数>铃重>株高>果枝始节>生育期,为选育彩色棉优势组合提供科学依据。
In this paper, the comprehensive analysis about main factors influencing F_1 yield of cross combinations on colored cotton has been completed by means of grey judgment. And the differences among these factors were compared. The result showed that the magnitude of grey relevancy between F_1 yield of cross combinations and each agronomic characteristic was in such an order as lint percentage>bolls/plant >fruit branch number> plant number/ unit area>boll weight>plant height >first fruiting node>development periods. It can provide a scientific basis for breed selection of colored cotton varieties.
